These components are critical to long-term reliability, channel balance, and authentic quadraphonic performance. • The amplifier circuits, tuner alignment, QS/SQ decoding circuits, signal path, dial illumination, meters, and front-panel controls are also carefully evaluated to determine the receiver's overall operating condition before restoration starts. During Restoration • Based on the inspection results, this QRX-8001 was restored according to HQaudios' technical standards while preserving the engineering and performance characteristics that have made this model one of Sansui's most respected quadraphonic receivers. • The power amplifier and preamplifier sections were professionally cleaned and serviced. Controls, switches, relays, and connectors were carefully cleaned to eliminate noise and ensure smooth operation. • The power supply, amplifier circuits, protection circuitry, and signal path were inspected and serviced as documented during restoration. Selected transistors and resistors within the signal path were also replaced to improve long-term reliability, reduce noise, and maintain the receiver's original operating characteristics. • FM/AM tuner performance, QS/SQ quadraphonic decoding, channel balance, input selection, speaker outputs, tone controls, protection circuitry, and all front-panel functions were tested and calibrated to restore dependable operation. • After the technical restoration was completed, the exterior was professionally cleaned and detailed to preserve the QRX-8001's original appearance while respecting the authentic character of vintage Sansui equipment. After Restoration • Once restoration had been completed, this QRX-8001 underwent comprehensive functional testing under real operating conditions. • Amplifier performance, quadraphonic decoding, tuner reception, channel balance, output power, protection circuitry, meter response, dial illumination, and all audio inputs and outputs were thoroughly tested to ensure the receiver performed as originally designed. • Finally, the unit underwent several hours of continuous listening tests through a complete vintage quadraphonic audio system to evaluate sound quality, operational stability, four-channel imaging, and overall real-world performance. • Only after successfully meeting HQaudios' restoration and testing standards was the Sansui QRX-8001 approved and prepared for its next owner. 7/ VIDEO TEST & SOUND DEMO We are happy to provide additional video, sound demo, or photos upon request. 8/ SUGGESTED PAIRING The Sansui QRX-8001 works beautifully with a wide range of restored vintage quadraphonic systems.
